Hello,
I am first time setting the http sink connector to send an JSON message. The connecter setup completed and i am able to send the test message. however, while i send the message from topic, i get this error though the schema has been added and the message is valid as per the validation.

Are you using JSON Schema? I believe that you’d hit this specific error if so and would want to use `io.confluent.connect.json.JsonSchemaConverter` instead of `org.apache.kafka.connect.json.JsonConverter`.
If that’s not it, could you please share a message and your connector config?
